Hi all,

I'm using OF4.1 to validate the flow on a NACA0015 3D wing in a steady angle of attack. The loads, pressure and flow fields are quite accurate, however I'm getting a U oscillation on pressure and suction sides, located where the octree stepping happens : see pics attached.

The settings are straight from OpenFOAM tutorials, and I'm using simplefoam. The mesh max non ortho is 65 and the computation is converged. Does anybody have an idea to improve this ? I've tried many different scheme and solution settings and still get the same issues.

Thanks !
